` Fig. 4; shows a verticai ransvei'se section a' pina track C. The i-ruck frame may' bclcon- Supported on Whe'eis B, adapted to traversev transversely across vthe axes' of ihe Wheeis. At each end ihe freek fran'ie is provided section D, carrying a hopper The section D comprises side hars di, hinged at d ite the upper part of the truck frame a Short distance from the end thereof. The side bars are adapted to be raised and ion'ered inside the side bars of 'the truck iframe. la order io raise and lower the hinged Sections, provide nach of hem with toehed segments F with which engage pin ione y" on a ehat f', carrying a handwvheei f2. Fig. 2 of the drawings indicates the raised and lov'er'ed posicions'of ehe hinged heforni showna their enter ends being open as Weii as being provided. with openhotton'ie. Each, truck carries a 'eonveyer heit H which 'is supported en its upper rnn hy :ioiiere z,

and ai; 'each end the heit passes around a, voiler mounted in the hinged section heini/een the side hars' (Z ins?, over the inner end of the hopper rEhe return portion ci the ioei is suitably guided and is conneet/ed with motor mechanism J. by which it is driven. The track' may be propelled hy motor mechanisnx K of any suitable kind operatively conneced with the Wheels.' By this motor mechanism. the track may be prepelis-d on die Hack i3 o an)F desired extent.

it viii be observed that a portion of the heit ,ectione The hoppeis are preferahiy of 1 il ai"` each end may be raised and lowered with the hinged section D. lllhen said section with the belt is in its raised position the belt may deliver material through the hopper l. 1When thc hinged section is lowerei'l to the dotted line position slioivn in Fig. 3 the belt is in position to receive inateiial from an adjacent unit conveyer. The manner in `which tivo unit convcyeis are connected and associated is indicated in Fig. rl`he belt H is supposed to niove in the direction indicated by the arrow. The hinged section D of the unit conveyor on the right-- hand side of Fig. 3 is raised, while the hinged section of the unit conveyor on the left-hand side of Fig. 3 is depressed or lov.- ered. Material carried by the belt H on the first truck in the series will be delivered through :its hopper E to tlie inclined upper run oi the belt H on the next unitconveyeland `Will be carried forward by said conveyer. Fig'. 3 also indicates by dotted lines.

how the hinged section on the unit conveyor at the right of 3 may be lowered to receiving position when the belt il is made to move in an opposite direction.

When brought together for congoint operation, the trucks are preferably coifinectedl by connecting bars L, which may. be readily detached when required. 0

In Fig. 6 l have indicated one Way in which the unit conveyors may be associated with each other and with a conveyer for supplying them and an apparatus tor unloading them. ln this figure of the draw-- ings M indicates car tracks provided with track hoppers m supplying a mainconveyer belt N which delivers to a hopper n which, may be mounted on a stationair indicates an apparatus of suite. le kind tor delivering material supplied by the unit conveyers to a pile of material P or t0 other places for storage. The unloading7 apparatos U is preferably of the kind shown, described and claimed in my application for Patent No. 223,302, filed Mar. 19, 1918. [is indicated a truck 0 having Wheels o', traveling on the track C, is provided with a conveyer belt 02, driven by motor mechanism o3, and .delivering to a hopper #which in turn supplies a delivery conveyor 05, mounted on a turn-table o". Material fed by the main conveyor N passes through the hopper 'n and may be delivered to the end or inclined portion of a unit conveyor or t0 the midclie portion thereof between its hinged ends. Material flied to unit conveyor No. l is delivered unit conveyor No. 2, and from this conreyer it passes to the conveyor o2 or' the unloadingn apparatus O. As before stated, the 'conveyor o is independently operated and the con veycr on cach one ot the. unit conveyors is independently operated. "ilhen starting a pile, of material only one iinit conveyer may bc used but as the pile increases in length an other unit conveyor may be brought into service Without in any way interfering with the operation of the main conveyor belt N or With the operation of the conveyor belt on the first unit conveyor in the series. llf'lien the size of the pile is still further increased another unit conveyor may be brought into service. rhis is preferably arranged on the saine track C as the other unitr l do not herein claim the system of conveying means comprising a main conveyor, tinit conveyors and unloading apparatus associated therewith, es such system is. claimed iii my application for Patent No. 208,355, .tiled Dec. 22, 1917,
